Refining Automotive Battery
Management Systems
with Lumped-Approach
Thermal Modeling
For India's transportation sector to meet its ambitious electrification goals, manufacturers must
accelerate the development of essential components, such as battery management systems.
I
ndia is a fast-growing market for electric vehicles (EVs),
with one study predicting that over 30 percent of the
vehicles sold in India will be electric by 2030. The battery
packs that power EVs are one of the main drivers of the
electric mobility revolution in India. To monitor and manage
battery pack performance and safety, packs are usually
equipped with a battery management system (BMS). A BMS
is an electronic system that monitors a battery's voltage, temperature,
coolant flow, and health and predicts several other
performance parameters, such as current variation and heat
generation, helping to extract optimum performance from a
battery pack.
The Role of Simulation in Developing
Accurate BMS
Exicom Tele-Systems Pvt. Ltd. designs, develops, and deploys
energy solutions, including the latest lithium-ion (Li-ion) battery
technologies. To date, it has deployed Li-ion battery solutions
totaling more than 1.8 GWh - among the highest in the world
by a single company. Exicom also offers charging solutions and
BMS for electric two-wheelers and light electric vehicles, which
are driving the growth of electric mobility in India.
At Exicom's R&D center in Gurugram, India, the techteam
led by Dr. Parmender Singh has developed
nology
a BMS that can be used to precisely monitor and manage
Li-ion batteries in applications across a
broad voltage range (up to 1000 V).
